TOUCH TECHNOLOGY CAPACITIVE This technology uses a sensor grid of micro fine wires integrated into the glass that covers the screen. Touch is detected because electrical characteristics of the sensor grid change when human finger is placed on the glass. Thanks to the glass overlay this technology is highly durable, and the touch function remains unaffected even if the glass is scratched. It offers perfect picture performance and will work with human finger (also latex gloved) and stylus pen.

  7. Celexon Electric Professional Plus V2.0 Battery Projector Screen 280 x 158 cm

    no Plug just Play The revolution of electric screens from celexon! The battery powered motorised screen from our well known Professional Plus series has been updated! The well known advantages have either remained or been improved: Unprecedented freedom of installation Saves cost, time and nerves and creates installation possibilities that no other electrical screen could offer. There is no easier and quicker way to put an electric screen into operation. No other electric screen can be installed more elegantly and unobtrusively. This electric projection screen does not require a permanent power connection, but is powered by an integrated lithium ion battery. It can be rolled up or unrolled up to 500 times and that only with one battery charge. This is normally sufficient for a whole year. No plug Just play. Simply hang it up and start using A radio remote control is already included in the box, so that the screen can be conveniently controlled remotely via the integrated receiver. You also have the option of combining this screen with other radio control systems from celexon. You can combine the projection screen with the celexon Professional 1 channel radio set, celexon Professional multi channel radio set or the celexon Professional radio trigger experience wireless freedom in a new way! Innovative technology Brilliant picture On our new matt white 4k projection screen fabric we have created an extremely fine surface structure which is also suitable for 8k projections. So you are well prepared for future standards and already enjoy your 4k content in pixel accurate reproduction on the battery screen from celexon.

This ensures a particularly long service life, because unlike pure PVC screen fabrics, celexon's MWHT 4K PET projection screen fabric is much more temperature stable (please note the enclosed instructions). It also has fire protection certification, is equipped with an anti mould coating and has an antistatic effect. A very homogeneous image reflection, pixel accurate and with a wide viewing angle makes our new 4k projection screen of 'TYPE D' ( diffuse reflecting) an ultimate choice for all living room cinemas, conference or training rooms or event halls. The gain of 1.0 (in accordance with DIN 19045 4) has been deliberately chosen to be only slightly brightening, so that colour values are not distorted too much (as is the case with higher gain screens) and optimum contrast values can be achieved for matt white screens. For reliable operation over the entire battery capacity, we install a lithium ion battery. LiOn's retain their performance (unlike conventional alkaline or nickel metal hydride batteries) over almost the entire capacity, the performance only drops at the very end, so your screen always runs reliably in or out at the same speed. When it comes to charging, simply connect the supplied charging adapter. This shows you the charging status via an LED and switches off automatically when fully charged. This protects the battery and offers a high level of charging safety . The built in LiOn battery can be charged several hundred times. This exceeds the regular lifetime of a screen considerably. In the box celexon battery screen motor Professional Plus V2.0Screen fabric: celexon matt white 4K PET projection screen fabric3 button radio remote control (up down stop)Charger with charge control indicator Cable 4m long with multi country adapterInstruction Screen handling instructionsincl. button cell battery CR2032, 3V for assumed normal use of 3 4 days week. 1 use day each Never charge rechargeable or rechargeable batteries unattended. Always disconnect the charging adapter from the screen after a full charge. Never store a LiOn battery completely empty for a long period of time (more than 4 weeks) and keep it away from temperature sources of more than 45 C in order to obtain an optimum service life.
